First, add up all the ages: 60 + 61 + 62 + 63 + 64 + 65 + 66 + 68 + 68 + 69 + 70 + 73 + 73 + 74 = 901
Next, divide the total sum by the number of senior citizens (14) to find the arithmetic mean age:
901 / 14 = 64.36
Therefore, the arithmetic mean age of the senior citizens is 64.36 years. Rounded to the nearest hundredth, the mean age is 64.36.
Health care issues are receiving much attention in both academic and political arenas. A sociologist recently conducted a survey of citizens over 60 years of age whose net worth is too high to qualify for Medicaid. The ages of 14 senior citizens were as follows:
60
61
62
63
64
65
66
68
68
69
70
73
73
74
Calculate the arithmetic mean age of the senior citizens to the nearest hundredth of a year.
84.45
66.86
69.65
61.45
